The following online calculator allows for the conversion of Volumetric Flow Rates given in MMSCFD (million standard cubic feet per day) to Mass Flow Rates such as kg/s, kg/hr, lb/s and lb/s. The calculator requires the following inputs:

• MMSCFD
• Molecular Weight
• Standard Temperature (Imperial)
• Standard Pressure (Imperial)
• Standard Temperature (Metric)
• Standard Pressure (Metric)

The following calculator is often useful in Acoustic Induced Vibration (AIV) assessments where a mass flow rate is not given in the Instrument Specification Sheet, the mass flow rate is required for the PWL calculation during the initial screening stage of an AIV assessment.

Note: As MMSCFD is an Imperial Unit, this must be taken into account when converting into Metric units therefore the standard values must be know for Imperial and Metric conditions.
